  Study of Factors Affecting the Copper Ore Leaching Process

  202369 · The high efficiency of copper extraction from the Satbayev deposit was due to the relatively low content of calcium and magnesium compounds in the ore compared with samples from other deposits. At the same time, in the sample of the Baytemir deposit, despite the relatively low extraction of 54.3% in 60 days, there was a tendency for the …

  Dissolution of natural serpentinite in mineral and organic acids

  200774 · Abundant resources of magnesium silicates make an interesting prospect for long-term storage of CO 2 by mineral carbonation. Several carbonation processes proposed in literature for CO 2 storage employ extraction of silicate minerals using a liquid solvent. In this study, the dissolution of natural serpentinite in respective solutions of …

  Extraction of magnesium oxide from magnesium silicate …

  The resulting MgCl2 solids were calcined at the following temperatures 550 °C, 650 °C, 750 °C, 850 °C to produce MgO. The MgO produced was characterised by XRD, TGA, XRF, BET and SEM. The MgO extraction by this method has a purity of 84%, suitable as a cement for civil engineering applications and raw material for carbon dioxide ...
